Data

Menlo Systems’ fiber-based femtosecond laser sources integrate the latest
achievements in fiber technology into easy-to-use products. Menlo Systems’unique figure 9® mode locking technology results in reproducible and long-term
stable operation. The ELMO with its all-fiber design guarantees excellent stability and low-noise operation. As seed source for fiber amplifiers the oscillator ismaintenance free, user installed and ready to use at the press of a single button.
In short: An OEM laser engineered for 24/7 operation.
